Description
Technical Field
The present invention relates to a filament winding device (filament winding device) and a filament winding method (filament winding method) for winding a fiber bundle impregnated with a resin around a wound member.
Background
A filament winding apparatus (hereinafter also referred to as FW apparatus) is known in which a fiber bundle impregnated with a resin is wound around a wound member. An example of the wound member includes a liner (liner) constituting a high-pressure container. In this case, the FW device winds the fiber bundles around the outer surface of the liner, so that a fiber-reinforced resin layer covering the liner to reinforce the liner can be formed.
In such FW devices, there are cases where the winding tension of the fiber bundle changes depending on the feeding speed of the fiber bundle to be fed to the wound member and the winding position of the fiber bundle on the wound member. When the winding tension of the fiber bundle changes along the allowable determination range set in advance according to the above-described supply speed and winding position, it can be determined that the winding of the fiber bundle is performed well.
For this reason, for example, japanese patent application laid-open No. 2007-268817 proposes a technique of continuously recording winding tension of a fiber bundle when winding the fiber bundle around a member to be wound, creating a tension map (fig. 7), and determining whether winding of the fiber bundle is good or not based on the tension map.
Disclosure of Invention
In the case where the determination of whether or not the tension is good is performed based on the tension map by the determination unit on the computer or the like, for example, as shown in fig. 7, it is conceivable to set an upper limit threshold value and a lower limit threshold value of the winding tension and compare the upper limit threshold value and the lower limit threshold value with the tension map. By this comparison, when a portion exceeding the upper threshold or a portion below the lower threshold is detected on the tension map, for example, as shown in NG1 of fig. 7, it can be determined that a winding failure of the fiber bundle has occurred.
However, the allowable determination range of the actual winding tension varies depending on the feeding speed and the winding position of the fiber bundle. Therefore, for example, as shown in NG2 of fig. 7, when the winding tension falls outside the allowable determination range while falling between the upper limit threshold and the lower limit threshold, it is not possible to determine that the winding tension is a winding failure of the fiber bundle. That is, in the determination of comparing the upper limit threshold value and the lower limit threshold value of the winding tension with the tension map as described above, it is possible that whether or not the winding of the fiber bundle is good cannot be determined with high accuracy.
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a filament winding device and a filament winding method that can determine whether winding of a fiber bundle is good with high accuracy.
The technical scheme of the invention is as follows: a fiber winding device for winding a fiber bundle impregnated with resin on a wound member, comprising: a winding unit that winds the fiber bundle around the wound member; a tension acquisition unit that detects a winding tension applied to the fiber bundle by the winding unit, and acquires a winding tension detection value; a supply speed acquisition unit that detects a supply speed at which the winding unit supplies the fiber bundle, and acquires a supply speed detection value; a storage unit that stores correlation information obtained by setting an allowable determination range of the winding tension based on a relation with the supply speed; and a determination unit that compares detection information obtained by associating the winding tension detection value with the supply speed detection value with the correlation information to determine whether or not winding of the fiber bundle is satisfactory.
The technical scheme of the invention is as follows: a fiber winding device for winding a fiber bundle impregnated with resin on a wound member, comprising: a winding unit that winds the fiber bundle around the wound member; a tension acquisition unit that detects a winding tension applied to the fiber bundle by the winding unit, and acquires a winding tension detection value; a winding position acquisition unit that detects a winding position at which the winding unit winds the fiber bundle, and acquires a winding position detection value; a storage unit that stores correlation information obtained by setting an allowable determination range of the winding tension based on a relation with the winding position; and a determination unit that compares detection information obtained by associating the winding tension detection value with the winding position detection value with the correlation information to determine whether or not winding of the fiber bundle is satisfactory.
The technical scheme of the invention is as follows: a fiber winding method for winding a fiber bundle impregnated with resin on a wound member, comprising: a winding step of winding the fiber bundle around the wound member; a detection value acquisition step of detecting a winding tension of the fiber bundle in the winding step to acquire a winding tension detection value, and detecting a supply speed of the fiber bundle in the winding step to acquire a supply speed detection value; and a determination step of determining whether or not the winding of the fiber bundle is satisfactory by comparing correlation information obtained by setting an allowable determination range of the winding tension based on a relation with the supply speed with detection information obtained by associating the winding tension detection value acquired in the detection value acquisition step with the supply speed detection value.

In the present invention, correlation information obtained by setting an allowable determination range of winding tension based on a relation with a supply speed or a winding position of a fiber bundle with respect to a member to be wound is obtained in advance. Further, the detection information is obtained by associating a winding tension detection value obtained when the fiber bundle is actually wound around the wound member with a supply speed detection value or a winding position detection value. Then, the detection information is compared with the correlation information to determine whether the winding of the fiber bundle is good.
Accordingly, it can be determined whether or not the winding tension is included in the allowable determination range corresponding to the feeding speed or the winding position of the fiber bundle. Therefore, it is possible to accurately determine whether or not the winding of the fiber bundle is good, compared with a case where, for example, the upper limit threshold value and the lower limit threshold value of the winding tension are compared with a tension line chart obtained by continuously recording the winding tension of the fiber bundle.
The above objects, features and advantages should be easily understood by the following description of the embodiments with reference to the attached drawings.

Detailed Description
The filament winding device and the filament winding method according to the present invention will be described in detail with reference to the drawings by referring to preferred embodiments. In the following drawings, the same reference numerals are given to components that exhibit the same or similar functions and effects, and overlapping descriptions may be omitted.
Next, an example will be described in which a liner 14 is used as a wound member 16 with respect to a filament winding apparatus (hereinafter also referred to as FW apparatus) 10 according to embodiment 1 of the present invention shown in fig. 1, wherein the liner 14 constitutes the high-pressure vessel 12 of fig. 2. Although not shown, the high-pressure vessel 12 is mounted on a vehicle body together with a fuel cell, for example, and is filled with hydrogen gas for supply to the fuel cell at high pressure.
As shown in fig. 2, the high-pressure vessel 12 has an inner liner 14 and a fiber-reinforced resin layer 18 covering the inner liner 14. The liner 14 has a cylindrical portion 20 having a substantially equal diameter in the axial direction and dome-shaped portions 22 provided on both sides of the cylindrical portion 20 in the axial direction, respectively. Preferable materials for the liner 14 include thermoplastic resins having hydrogen barrier properties such as high-density polyethylene. Openings are provided at both ends of the liner 14, respectively, and a mouthpiece 24 is mounted on these openings.
The fiber-reinforced resin layer 18 is formed by winding a ribbon-shaped fiber bundle 26 (prepreg) impregnated with resin of fig. 1 around the outer surface of the liner 14 in a predetermined number of layers, and then curing the resin contained in the fiber bundle 26. In order to obtain the fiber-reinforced resin layer 18 of the high-pressure vessel 12, the FW apparatus 10 according to the present embodiment winds the fiber bundle 26 around the outer surface of the liner 14. However, the FW apparatus 10 can be used for an application of winding the fiber bundle 26 around the wound member 16 other than the liner 14.
Examples of the fibers constituting the fiber bundle 26 include carbon fibers, glass fibers, and aramid fibers. Examples of the resin constituting the fiber bundles 26 include epoxy resin, phenolic resin, and unsaturated polyester resin.
The FW apparatus 10 mainly includes a winding portion 28, a detecting portion 30, and a control portion 32. The winding portion 28 has an unwinding mechanism 34, a tension adjusting mechanism 36, a winding head 38, and a rotation supporting mechanism 40.
The deployment mechanism 34 supplies the fiber bundle 26 to the liner 14. As such a deployment mechanism 34, a known configuration can be adopted. Accordingly, although not shown in detail, the unwinding mechanism 34 may be constituted by, for example, a creel (bobbin) that supports a bobbin (bobbin) around which the fiber bundle 26 is wound in advance, an unwinding roller, or the like; the unwinding roller unwinds the fiber bundle 26 from the spool to the downstream side in the conveying direction.
The tension adjustment mechanism 36 adjusts the tension in the conveyance direction of the fiber bundle 26 unwound from the unwinding mechanism 34, thereby setting the winding tension of the fiber bundle 26 wound around the liner 14 to a predetermined set value. As the tension adjustment mechanism 36, a known structure can be adopted. Therefore, although not shown in detail, the tension adjusting mechanism 36 may be constituted by a dancer roll (dancer roll) that abuts against the fiber bundle 26 from a direction intersecting the conveying direction, a cylinder, or the like; the cylinder presses the dancer roller against the fiber bundle 26 to apply a predetermined tension to the fiber bundle 26. The tension adjusting mechanism 36 is not limited to the structure having the dancer roller and the cylinder described above.
The winding head 38 guides the fiber bundle 26 unwound from the unwinding mechanism 34 to the liner 14. The winding head 38 is supported by a support rail, not shown, so as to be movable in the axial direction of the liner 14, and in the horizontal direction and the up-down direction orthogonal to the axial direction, for example. The winding head 38 may be rotatable about the extending direction of the fiber bundle 26 wound around the liner 14.
The winding position (hereinafter also simply referred to as winding position) of the wound fiber bundle 26 of the liner 14 is controlled by adjusting the relative position of the winding head 38 with respect to the liner 14 based on the control of the control unit 32. The winding head 38 is provided with a winding position acquisition unit 42, and the winding position acquisition unit 42 obtains a winding position detection value by measuring the relative position of the winding head 38 with respect to the liner 14, for example. In the FW apparatus 10 according to embodiment 1, the winding position obtaining unit 42 is not an essential component.
The rotation support mechanism 40 includes a support portion, not shown, that rotatably supports the liner 14 about its axis, and a rotation drive portion 44; the rotation driving unit 44 rotates the liner 14. The fiber bundle 26 is discharged from the unwinding mechanism 34 while the winding head 38 is moved relative to the liner 14 driven to rotate by the rotation support mechanism 40, whereby the fiber bundle 26 can be wound around the outer surface of the liner 14 while changing the winding position.
The control unit 32 adjusts the rotational speed of the unwinding roller of the unwinding mechanism, the rotational speed of the rotary driving unit 44 for rotating the liner 14, and the like in the winding unit 28, thereby setting the feeding speed (hereinafter also simply referred to as feeding speed) of the fiber bundle 26 to the liner 14.
In the case where the liner 14 having the cylindrical portion 20 and the dome-shaped portion 22 is used as the wound member 16 as in the present embodiment, for example, the feeding speed when the fiber bundle 26 is wound around the dome-shaped portion 22 is slower than the feeding speed when the fiber bundle 26 is wound around the cylindrical portion 20.
The detecting unit 30 acquires detection information in which a winding tension detection value, which is a value obtained by detecting the actual winding tension of the winding unit 28, and a supply speed detection value are associated with each other; the supply speed detection value is a value obtained by detecting the actual supply speed of the winding unit 28. Specifically, the detection unit 30 includes a tension acquisition unit 46, a feed speed acquisition unit 48, and a processing unit 50.
The tension acquisition unit 46 measures the actual winding tension of the fiber bundle 26 after passing through the tension adjustment mechanism 36 to obtain a winding tension detection value. The tension acquiring section 46 has, for example, a set of guide rollers 52, a pressing roller 54, and a tension sensor 56, wherein the set of guide rollers 52 are arranged at intervals in the conveying direction; the pressing roller 54 applies a pressing force to the fiber bundle 26 between these guide rollers 52 from a direction intersecting the conveying direction; the tension sensor 56 obtains a winding tension detection value based on the force acting on the pressing roller 54 from the fiber bundle 26. The winding tension detection value obtained by the tension sensor 56 is sent to the processing unit 50 provided in the control unit 32. The tension acquiring unit 46 is not limited to the above configuration, and may be configured to be capable of measuring the winding tension.
The supply speed acquisition unit 48 is provided near the tension acquisition unit 46, for example, and measures the actual supply speed of the fiber bundle 26 to obtain a supply speed detection value. The supply speed acquisition unit 48 includes, for example, a rotating roller 58 and a speed sensor 60, wherein the rotating roller 58 rotates in contact with the fiber bundle 26 being conveyed; the speed sensor 60 obtains a supply speed detection value from the rotational speed of the rotating roller 58. The supply speed detection value obtained by the speed sensor 60 is sent to the processing section 50 of the control section 32. The supply speed obtaining unit 48 is not limited to the above configuration, and may be configured to be capable of measuring the supply speed. For example, instead of obtaining the supply speed detection value from the rotation speed of the rotating roller 58, the speed sensor 60 of the supply speed obtaining portion 48 may obtain the supply speed detection value from the rotation speed of any one of the guide rollers 52 of the tension obtaining portion 46.
The processing unit 50 obtains detection information by associating a winding tension detection value with a supply speed detection value at the time of measuring the winding tension detection value (see black dots in fig. 3). The detecting unit 30 may also obtain a correlation (hereinafter also referred to as a detection correlation) between the supply speed detection values and the winding tension detection values indicated by a plurality of black dots in fig. 3 by associating the plurality of winding tension detection values and the plurality of supply speed detection values with each other by the processing unit 50.
The control unit 32 includes a storage unit 62 and a determination unit 64 in addition to the processing unit 50. The control unit 32 is configured as a computer having a CPU, a memory, and the like, which are not shown. The CPU executes a predetermined operation in accordance with a control program, and performs various processes and controls related to the FW apparatus 10. That is, the control unit 32 receives detection signals from various sensors included in the FW apparatus 10, and outputs drive signals to the respective units.
In the present embodiment, the memory of the control unit 32 can be made to function as the storage unit 62. Further, the CPU reads and executes the control program stored in the memory, and the control program enables hardware such as the CPU to function as the processing unit 50 and the determination unit 64. The function of the control unit 32 may be realized in hardware based on the circuit configuration of the control unit 32, in addition to being realized in software.
The storage unit 62 stores information on the relation between the supply speed and the allowable determination range of the winding tension. In the present embodiment, the correlation information is represented by an elliptical shape indicated by a broken line L1 in fig. 3, and the inside surrounded by the broken line L1 becomes the allowable determination range. That is, the allowable determination range of winding tension when the supply speed is V1 is RV1. The allowable determination range of winding tension when the supply speed is V2 is RV2.
The winding tension shown in the allowable determination range becomes smaller when the feeding speed is small, and becomes larger when the feeding speed is large. That is, the supply speed changes according to winding of the fiber bundle 26 around the cylindrical portion 20 and the dome-shaped portion 22 of the wound member 16, and accordingly, the allowable determination range of the winding tension also changes.
The determination unit 64 compares the correlation information stored in the storage unit 62 with the detection information obtained by the detection unit 30 to determine whether or not the winding of the fiber bundle 26 is good. Specifically, the determination unit 64 determines whether or not the winding tension detection value in the detection information is included in the allowable determination range of the correlation information at the supply speed (supply speed detection value) in which the winding tension detection value is correlated with the detection information. The determination unit 64 may compare the correlation information stored in the storage unit 62 with the detection correlation obtained by the detection unit 30 to determine whether or not the winding of the fiber bundle 26 is satisfactory.
The determination unit 64 may determine whether or not 1 or more pieces of detection information selected from among the plurality of pieces of detection information shown by black dots in fig. 3 are within a set allowable range surrounded by a broken line L1, or whether or not all or a predetermined proportion of the pieces of detection information shown by black dots in fig. 3 are within a set allowable range surrounded by a broken line L1, for example.
Regarding the detection information within the set allowable range surrounded by the broken line L1 as shown by DOK in fig. 3, since the winding of the fiber bundle 26 is performed at the winding tension within the allowable determination range corresponding to the supply speed, the determination unit 64 determines that the winding is performed satisfactorily. On the other hand, regarding the detection information that is outside the set allowable range surrounded by the broken line L1 as shown by DNG1 and DNG2 in fig. 3, since the winding of the fiber bundle 26 is performed at a winding tension lower or higher than the allowable determination range corresponding to the supply speed, it is determined that the winding is defective.
The FW device 10 according to the present embodiment is basically configured as described above. The filament winding method (hereinafter also referred to as FW method) according to the present embodiment will be described below by taking the case where the liner 14 is the wound member 16 as an example, using the FW apparatus 10 with reference to fig. 1 to 4.
In this FW method, a winding process (S1 in fig. 4) of winding the fiber bundle 26 around the liner 14 is performed. In the winding step, the winding roller of the winding mechanism 34 is rotated to wind the fiber bundle 26 toward the liner 14, and the liner 14 is rotated by the rotation driving unit 44 of the rotation support mechanism 40 to wind the fiber bundle 26 around the liner 14. At this time, the control unit 32 changes the winding position by moving the winding head 38, and thereby performs, for example, hoop winding (loop winding) or helical winding (helical winding) on the liner 14.
For example, when the winding position is located at the substantially center in the axial direction of the cylindrical portion 20, the feeding speed is the fastest (becomes the maximum speed). When the winding position is located near the end of the dome-shaped portion 22 on the interface 24 side in the axial direction, the feeding speed is the slowest (becomes the minimum speed). The supply speed is continuously changed between the maximum speed and the minimum speed in response to the change in the winding position.
As described above, the supply speed changes in accordance with the change in the winding position, and thus the actual winding tension in the winding process also changes with respect to the set value set by the tension adjustment mechanism 36. In the present embodiment, the winding tension tends to increase when the feeding speed increases, and tends to decrease when the feeding speed decreases.
Next, a detection value acquisition step (S2 of fig. 4) is performed in which an actual winding tension in the winding step is detected to acquire a winding tension detection value, and an actual supply speed in the winding step is detected to acquire a supply speed detection value. Then, the winding tension detection value and the supply speed detection value acquired in the detection value acquisition step are correlated to obtain detection information.
Next, a determination step (S3 in fig. 4) is performed in which the correlation information and the detection information are compared to determine whether or not the winding of the fiber bundle 26 is good. In the determination step, it is determined whether or not the winding tension detection value of the detection information is included in an allowable determination range at a supply speed (supply speed detection value) in association with the winding tension detection value.
When it is determined that the winding tension detection value in the detection information is included in the allowable determination range (corresponding to the allowable determination range) (yes in S3 of fig. 4), it is determined that the winding is performed satisfactorily (S4 of fig. 4). On the other hand, when it is determined that the winding tension detection value in the detection information is not included in the corresponding allowable determination range (S3: no in fig. 4), it is determined that a winding failure has occurred (S5 in fig. 4).
The winding process may be performed while the winding process is performed to determine whether the winding of the fiber bundle 26 is good, or the winding process may be performed after the winding process is completed to determine whether the winding of the fiber bundle 26 is good.
That is, when the fiber bundle 26 wound around the outer surface of the liner 14 reaches the thickness (number of layers) required for forming the fiber-reinforced resin layer 18, the winding process is completed. When the determination step is performed after the completion of the winding step, a plurality of pieces of detection information, which are obtained by associating a plurality of supply speed detection values and a plurality of winding tension detection values obtained in the detection value obtaining step, respectively, are recorded. The detected correlation obtained in this way can be compared with the correlation information to determine whether the winding is good.
From the above, in the FW apparatus 10 and the FW method according to embodiment 1, correlation information obtained by setting an allowable determination range of winding tension based on the relation with the supply speed is obtained in advance. Further, the detection information is obtained by associating a winding tension detection value obtained when the fiber bundle 26 is actually wound around the liner 14 with a supply speed detection value. Then, the detection information is compared with the correlation information to determine whether the winding of the fiber bundle 26 is good.
For example, as shown in DOK of fig. 3, when the detection information falls within the allowable determination range surrounded by the broken line L1 indicating the correlation information, it can be determined that the winding is performed satisfactorily. Further, as shown in DNG1 and DNG2 of fig. 3, if the detection information is outside the allowable determination range surrounded by the broken line L1 indicating the correlation information, it can be determined that the winding is defective.
Here, for example, when the upper threshold H1 and the lower threshold H2 of the winding tension shown by the one-dot chain line in fig. 3 are compared with the detection information, it can be determined that the winding failure has occurred only based on the detection information shown by the DNG 1. That is, it cannot be determined that winding failure has occurred based on the detection information shown by DNG 2.
In contrast, in the FW apparatus 10 and the FW method according to embodiment 1, it is possible to determine that a winding failure has occurred based on not only the detection information shown by DNG1 but also the detection information shown by DNG2 between the upper limit threshold H1 and the lower limit threshold H2, as described above. In this way, it can be determined whether or not the winding tension detection value is included in the allowable determination range that varies according to the supply speed of the fiber bundle 26, and therefore, it can be determined with high accuracy whether or not the winding of the fiber bundle 26 is good.
In the FW apparatus 10 according to embodiment 1 described above, the wound member 16 is the liner 14 constituting the high-pressure vessel 12, and has the cylindrical portion 20 and the dome-shaped portion 22, and the supply speed at the dome-shaped portion 22 is slower than the supply speed at the cylindrical portion 20. In the FW method according to embodiment 1, the wound member 16 is the liner 14 constituting the high-pressure vessel 12, and has the tubular portion 20 and the dome-shaped portion 22, and in the winding step, the supply speed at the dome-shaped portion 22 is slower than the supply speed at the tubular portion 20. When the feeding speed of the fiber bundle 26 is changed by using the liner 14 as the wound member 16, it is possible to determine whether or not the winding is good particularly effectively and with high accuracy.
The FW apparatus 70 and the FW method according to embodiment 2 will be described with reference to fig. 5 and 6. The FW apparatus 70 according to embodiment 2 shown in fig. 5 mainly includes a winding portion 72, a detecting portion 74, and a control portion 76.
The winding portion 72 of fig. 5 winds the fiber bundle 26 around the liner 14 while continuously changing the winding position of the wound fiber bundle 26 between the cylindrical portion 20 and the dome-shaped portion 22 under the control of the control portion 76.
The detecting unit 74 of fig. 5 may have substantially the same configuration as the detecting unit 30 of fig. 1 except that the detecting unit 74 acquires detection information obtained by associating a winding tension detection value, which is a value obtained by detecting the actual winding tension of the winding unit 72, with a winding position detection value under the control of the control unit 76; the winding position detection value is a value obtained by detecting the actual winding position of the winding portion 72. That is, the detecting section 74 includes the winding position acquiring section 42 instead of the supply speed acquiring section 48. The processing unit 78 of the detecting unit 74 associates the measurement results of the tension acquiring unit 46 and the winding position acquiring unit 42.
Specifically, the processing unit 78 obtains the detection information by associating the winding tension detection value with the winding position detection value at the time of measuring the winding tension detection value (solid line in fig. 6). The detecting unit 74 may also obtain a correlation (detected correlation) between the winding position detection value and the winding tension detection value shown by continuous solid lines in fig. 6 by associating the plurality of winding tension detection values and the plurality of winding position detection values with each other by the processing unit 78.
The storage unit 80 of the control unit 76 stores correlation information obtained by setting an allowable determination range of the winding tension based on the relationship with the winding position. In the present embodiment, the correlation information is represented by 2 broken lines L2 and L3 in fig. 6, and these broken lines L2 and L3 are allowed to be determined in a range between them. That is, the allowable determination range of the winding tension when the winding position is P1 is RP1. The allowable determination range of the winding tension when the winding position is P2 is RP2.
The winding tension shown in the allowable determination range becomes smaller when the winding position is in the dome-shaped portion 22 and becomes larger when the winding position is in the cylindrical portion 20. That is, as the winding position is changed, the allowable determination range of the winding tension is also changed. In fig. 6, the wave number of the waveform detection correlation and the correlation information corresponds to the number of layers of the fiber bundle 26 formed by winding the fiber bundle 26 around the outer surface of the liner 14.
The determination unit 82 of the control unit 76 compares the correlation information stored in the storage unit 80 with the detection information obtained by the detection unit 74 to determine whether or not the winding of the fiber bundle 26 is satisfactory. Specifically, the determination unit 82 determines whether or not the winding tension detection value in the detection information is included in the allowable determination range of the correlation information at the winding position (winding position detection value) in which the winding tension detection value is correlated. The determination unit 82 may compare the correlation information stored in the storage unit 80 with the detected correlation obtained by the detection unit 74 to determine whether or not the winding of the fiber bundle 26 is satisfactory.
The determination unit 82 may determine whether or not a part of the detection information shown by the solid line in fig. 6 falls within a set allowable range between the broken lines L2 and L3, or whether or not all or a predetermined proportion of the detection information falls within a set allowable range between the broken lines L2 and L3.
For example, in the FW method according to embodiment 2, which can be performed using the FW apparatus 70 configured as described above, a winding process (S1 in fig. 4) of winding the fiber bundle 26 around the liner 14 is performed. In the winding step, the winding roller of the winding mechanism 34 is rotated to wind the fiber bundle 26 toward the liner 14, and the liner 14 is rotated by the rotation driving unit 44 of the rotation support mechanism 40 to wind the fiber bundle 26 around the liner 14. At this time, the control unit 76 changes the winding position by moving the winding head 38, and thereby performs, for example, hoop winding and spiral winding on the liner 14.
The actual winding tension in the winding process may be changed with respect to the set value set by the tension adjustment mechanism 36 in response to the change in the winding position as described above. In the present embodiment, the winding tension tends to be high when the winding position is in the cylindrical portion 20, and tends to be low when the winding position is in the dome-shaped portion 22.
Next, a detection value acquisition process (S2 in fig. 4) is performed in which the winding tension in the winding process is detected to acquire a winding tension detection value, and the winding position in the winding process is detected to acquire a winding position detection value. Then, the detected value of the winding tension obtained in the detected value obtaining step is correlated with the detected value of the winding position to obtain the detected information.
Next, a determination step (S3 in fig. 4) is performed in which the correlation information and the detection information are compared to determine whether or not the winding of the fiber bundle 26 is good. In the determination step, it is determined whether or not the winding tension detection value of the detection information is included in the allowable determination range at the winding position (winding position detection value) in association with the winding tension detection value.
When it is determined that the winding tension detection value in the detection information is included in the allowable determination range (corresponding to the allowable determination range) (yes in S3 of fig. 4), it is determined that the winding is performed satisfactorily (S4 of fig. 4). On the other hand, when it is determined that the winding tension detection value in the detection information is not included in the corresponding allowable determination range (S3: no in fig. 4), it is determined that a winding failure has occurred (S5 in fig. 4).
The winding process may be performed while the winding process is performed to determine whether the winding of the fiber bundle 26 is good, or the winding process may be performed after the winding process is completed to determine whether the winding of the fiber bundle 26 is good. When the determination step is performed after the completion of the winding step, a plurality of pieces of detection information, which are obtained by associating a plurality of winding position detection values and a plurality of winding tension detection values acquired in the detection value acquisition step, respectively, are recorded. Whether or not the winding is good can be determined by comparing the detected correlation thus obtained with the correlation information.
From the above, in the FW apparatus 70 and the FW method according to embodiment 2, correlation information obtained by setting the allowable determination range of the winding tension based on the relation with the winding position is obtained in advance. Further, the detection information is obtained by associating a winding tension detection value obtained when the fiber bundle 26 is actually wound around the liner 14 with a winding position detection value. Then, the detection information is compared with the correlation information to determine whether the winding of the fiber bundle 26 is good.
For example, as shown in DOK of fig. 6, when the detection information falls within the allowable determination range between the broken lines L2 and L3 indicating the correlation information, it can be determined that the winding is performed satisfactorily. Further, as shown in DNG1 and DNG2 of fig. 6, if the detection information is outside the allowable determination range between the broken lines L2 and L3 indicating the correlation information, it can be determined that the winding is defective.
Here, for example, when the upper limit threshold H1 and the lower limit threshold H2 of the winding tension shown by the one-dot chain line in fig. 6 are compared with the detection information shown by the solid line in fig. 6, it is possible to determine that the winding failure has occurred only based on the detection information shown by the DNG 1. That is, based on the detection information shown in DNG2, it cannot be determined that winding failure has occurred.
In contrast, in the FW apparatus 70 and the FW method according to embodiment 2, it is possible to determine that a winding failure has occurred based on not only the detection information shown by DNG1 but also the detection information shown by DNG2 between the upper limit threshold H1 and the lower limit threshold H2, as described above. In this way, whether or not the winding tension detection value is included in the allowable determination range that varies according to the winding position of the fiber bundle 26 can be determined, and whether or not the winding of the fiber bundle 26 is good can be determined with high accuracy.
In the FW apparatus 70 according to embodiment 2, the wound member 16 is the liner 14 constituting the high-pressure vessel 12, and has the cylindrical portion 20 and the dome-shaped portion 22, and the winding portion 72 winds the fiber bundle 26 around the wound member 16 while continuously changing the winding position between the cylindrical portion 20 and the dome-shaped portion 22. In the FW method according to embodiment 2, the wound member 16 is the liner 14 constituting the high-pressure vessel 12, and has the cylindrical portion 20 and the dome-shaped portion 22, and the fiber bundle 26 is wound around the wound member 16 while continuously changing the winding position between the cylindrical portion 20 and the dome-shaped portion 22 in the winding step. When the winding position of the fiber bundle 26 is continuously changed by using the liner 14 as the wound member 16, it is possible to determine whether or not the winding is good particularly effectively and with high accuracy.
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
